Galgoczy, Jr., Cleveland, Ohio, as- ;signor ofone-fourth to Frank Bucsi, Cleveland, Ohio Application February 1, 1938,Serial No. 188,150 3 claims. (01. 98-44) My invention relates toimprovements in window ventilators of the type adapted to be interposedbetween the window sash and window sill and the principal object of theinvention is to 5 provide a ventilator of the type indicated equipped totrap breezes blowing across the window from opposite directions and todeflect the same inwardly of said window.

Other objects of the invention are toprovide 10 a device of thecharacter and for the purpose above set forth which may be readilyapplied, and removed, is strong and durable, light in weight, andinexpensive to manufacture.

To the accomplishment of the above and sub- 15 ordinate objectspresently appearing a preferred embodiment of my invention has beenillustrated in the accompanying drawings, treated in detail in thesucceeding description and defined in the claims appended hereto. 20 Insaid drawings: 1 Figure 1 is a view in horizontal transverse section ofa. window equipped according to my invention,

Figure 2 is a detail view in vertical transverse 25 section taken on theline 2-2 of Figure 1 looking in the direction indicated by the arrowsand drawn to an enlarged scale,

Figure 3 is a view in vertical transverse section taken on the line 3-3of Figure 1 looking 30 in the direction indicated by the arrows,

Figure 4 is a view in horizontal section taken on the line 4-4 of Figure3 looking downwardly, and

Figure 5 is a fragmentary view in side eleva- 35 tion of one of theclips and bails the purpose of which will presently appear.

Referring to the drawings by numerals, the device of my inventioncomprises an extensible window screen I having a pair of laterally slid-4 ing overlapping sections 2 and 3 adapted to be interposed between thelower sash 4 of the window and the window-sill 6, and an adjustabledeflector unit 1 extending outwardly from said screen I centrallythereof and beyond the win- 45 dow.

The deflector unit 1 comprises a rectangular upstanding baflle plate 8of light flexible metal, such as sheet tin, secured at one end, in amanner presently described, to the edges of the screen 50 l and of awidth coinciding substantially with the height of the screen I, and alength to extend well out beyond the window casing 9.

Secured at its rear edge to the baffle plate 8, as by soldering, notshown, is a second shorter 55 baille plate I U of a similar materialextending alongside approximately the outer half of the plate 8. Fromthe point of connection on plate I 0 the plate 8 has its upper edge andalso its lower edge bent or crimped, as at H and I2, to reinforcetheinner half of the said plate 8 against 5 lateral bending or flexing.The outer half of said plate 8 and the plate II) are free tobe flexed orbent laterally in opposite directions into separated relation to formconcave deflectors functioning in conjunction with the inner half of the10 plate 8 to trap breezes, or air currents, blowing across the windowin opposite directions and deflect the same inwardly of the window 5.

The described deflector unit I is secured to the screen I as follows.The rear edge of .the plate 8 is bent upon itself to form a verticallyextending socket l3 along said edge of rectangular cross section. A pairof upper and lower-right-angled metal brackets l4 and I5 are interposedbetween the upper edge of the screen I and the sash 4, on the one hand,and between the lower edge of said screen and the window sill 6 on theother hand, said brackets fitting around the edges of the screen 1adjacent the inner ends of the sections 2 and 3, and having right-angledends I6 fitting into the upper and lower ends of said socketrespectively. The upper bracket M has an upstanding extension I! adaptedto bear against the inner face of the sash 4 to hold the top edge of thescreen I against displacement outwardly of the window under the weightof the unit 1. A set screw l8 in the upper bracket l4 adapted to beturned against the inner side of the screen I provides for securing theunit in a vertical upstanding position.

The outer half of the plate 8 and the plate II] are held in laterallybent position by the following means. A pair of U-shaped clips l9 areslidably mounted on the top edge of the screen I to straddle the samefor adjustment along the 0 outer ends of the sections 2 and 3,respectively, into different set positions established by .a set screw20 extending from the inner side of each clip I9 and adapted to bearagainst the appropriate sections. A pair of V-shaped rodlike bailshaving upper and lower arms 22 are suitably mounted at the closed endsthereof, as at 23, on the clips l9, respectively, for lateral swingingmovement. The free ends of the arms 22 of one bail are pivotallyconnected to the plate 8 adjacent the upper and lower edges thereof .andcontiguous the outer end of said plate, and the free ends of the otherbail are similarly connected to the plate I 0. Preferably the connectionof the arms 22 to the plates 8 and I0 takes the form of sleevelike ears24 suitably secured to said plates, the arms 22 being bent as at 25, toextend into said ears.

As will be clear, by shifting the clips I9 along the screen I intodifierent set positions, the outer half of plate 8 and plate l0 may beflexed into different curvatures or permitted to react intosubstantially straight positions as occasion may require. The outer halfof plate B and theplate ID are provided with vertically extending'iouvres 26 whereby wind blowing directly against the outer sidesthereof may pass there-through.

As indicated by the arrows in Figure, 1 the described invention providesfor trappingend deflecting breeze or air currentsjblowingacross thewindow from the right-handsidethereof, so that air is caused to enterthe window on one side of the deflector unit, while; air. currentsblowing across said window from the left-hand side thereof are similarlycaused to enter the window on the left-han d side of said deflector unitand air blowing directly into the window is in no 'way blocked by, saiddeflector unit.

The foregoing' will, it s believed, sum-cg to part a clear understandingof the construction,

operation andadvafitages Of my invention wit out further explanation. v
